BOTTLE-STO PPER.

SPECIFICATION forming part of Letters Patent No. 360,467, dated April 5,1887.

Application led August 18, 1886. Serial No. 211,226. (No model.)

To all whom it may concern.-

Be it known that I, ALBERT I-I. PETERSON, a citizen of the UnitedStates, residing at Philadelphia, Pennsylvania, have invented certainImprovements in Bottle Stoppers, of which the following is aspecication.

My invention consists of certain improvements in the construction ofbottle-stoppers for which Iapplied for Letters Patent ofthe UnitedStates April 8, 1886, Serial No. 198,220.

Ihe main objects of my invention are to facilitat the closure of thebottle, to secure a tight closure, obviate liability of the stopperbeing opened by accidental blows, and to cheapen the construction. Theseobjects I attainin the manner which I will now proceed to describe.

I n the accompanying drawings, Figure 1 is a side view, partly insection, of abottle-neck provided with my improved stopper. Fig. 2 is asimilar view showing the stopper about to be closed. Fig. 3 isa view ofthe device on the fastening side.' Fig. 4 is a perspective view of theimproved form of yoke and lever. Fig. 5 is avertical section of mybottle-stopper provided with an improved form of valve to adapt it foruse with aerated liquids and showing the valve open, and Fig. 6 is aperspective view of the valve detached.

A represents the neck of the bottle,provided with the neck-wire a, toone side of which the stopper B is connected by a link, D, adapted t0A aloop or lug, b, on the stopper. I prefer to form this link ofthe samepiece of wire as the neck-band a and to put a twist, d, in the link, sothat should the fastening get slack it can be tightened at any time byincreasing the twist. The lug` b on the opposite side of the stopperreceives a curved link, E, for connection with the locking-lever F,which is adapted to act in connection with a yoke, G, secured to theoutside of the bottle-neck by the neck-wire a.

The rubber portion B of the stopper, which is fitted over and held bythe metal button in the usual way, is made concave on the under side, asshownin Fig. 2, in order thatwhen the stopper is forced down to its seatthe rubber may more readily spread around the edge to form a tightclosure, as shown in Fig. 1.

The link E, I make of the curved formillus trated in the drawings, andof spring-wire, so that it will constitute a spring, and when thestopper gets loose by repeated use or stretching ofthe wires or links itmay be tightened up, and an increased pressure obtainedby increasing orrestoring the bend of the wire-link E.

In my former stopper the link E is passed through an opening of thelever F; but in my presentinvention I dispense with the neccessity ofdrilling this opening by casting on the sides of the lever fingers e,which can Vbe cast in an openform, to be passed through eyes at thelower end of the two-armed link E, and then bent to form a closed eye,as illustrated in the drawings.

In my former stopper the yoke G was provided at its upper end with anotch for the introduction of the hooked nose of the lever F, and at itslower end with fingers g, for the protection and guidance of `lateralproj ectionsf on the lever F. In my present stopper I retain theprotecting fingers and projections last referred to, but I replace thenotch at the upper end of the yoke by a T-head, g', and fork the upperhooked end of the lever F for engagement therewith, so that the forksengage opposite sides ofthe T-head. By this construction the lever canbe more readily engaged with the yoke to close the stopper, and whenclosed it is more firmly held, so that there is less liability of thestopper being opened by accidental blows.

IVhere the stopper is to be used for aerated liquids, I make use oftheform of valve illustrated in Figs. 5 and 6. This valve consists of asmall inverted cup, s, having secured to it spring-fingers s', hooked attheir upper ends and preferably stamped out of sheet metal. Thesefingers are adapted to a vertical opening in t-he stopper, so as toallow a limited ver# tical play of the valve'toward and from the seat inthe rubber of the stopper. The ,upper hooked ends of the spring-fingerscome in contact with a shoulder in the opening in the stopper when thevalve is open, as shown in the drawings.

In filling the bottle with aerated liquid, the stopper is iirst closedand the iilling-nozzle pressed into the opening in the top of thestopper, so as to keep the valve open during t-he filling operation.When the iillingnozzle is removed, the pressure on the interior of thebottle will close the valve by bringing its cup s against the seatformed by the rubber lining looking devices with e valve consisting of aofthe stopper. cup, s', and hooked spring-fingers s', adapted I claim asmy inventionto a vertical opening in the stopper7 all sub- I5 1.
